VENTILATED-CORNCRIB-FLOOR MOLD.

Application filed June 7, 1921.

To all to ham it may com-cm Be it known that I, EDWIN L. Peon, a citizen of the United States, and a resident of Kingsley, in the county of Plymouth and State of Iowa, have invented certain new and useful Ventilated-Corncrib-Floor Molds, of which the following is a specification The object of my invention is to provide a ventilated corn crib floor structure which is made of concrete, and which is 01' a single unit, the structure being easily poured and comparatively cheap.

More particularly my invention relates to a floor for corn cribs which floor is placed above the ground level and set upon piers which are poured at the same time that the floor is poured, so as to have the piers and the floor structure of a single unit, whereby any cracks and openings will be avoided so as to make the crib mouse proof.

Still another object is to provide a door structure which is elevated above the ground level, which floor structure and supporting piers may be poured after the crib has been erected, by the use of forms which are casiiy assembled and disassembled.

Still another object is to provide knockdown forms which may be set within the crib for supporting the floor and the piers while the mass of material is permitted to set. The forms being so provided that they may be easily collapsed and removed from. below the floor structure.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings. in which:

Figure l is a view of the lower end of a corn crib With my improved floor structure therein.

Specification of Letters Patent.

Patented July 11, 1922. Serial No. 475,597.

Figure (3 is one of the forms for the supporting piers which are set against the side of the crib; and

Figure T is a perspective view of one of the center forms for the piers.

In the accompanying drawings I have used the reference numeral 10 to indicate generally a crib for the storing of corn or other grain, which is made up of a number of ventilated building blocks.

It will be understood that any type of ventilated building blocks may be used in the construction of the crib; in my application I have shown the blocks of the tvpe illustrated by my co-pending application, Serial ,N uml'u-r 469.916 filed IVIay 16, 1.921.

The crib H) is circular in outline and the blocks are set upon a foundation 11 which is 'u'eterablv set so that its upper edge is slightly above the ground level as clearly iilustraled in Figure 3 of the drawings.

It will be understood that in grain cribs, it is highly desirable to have the floor structure elevated above the ground so as to permit ventilation to pass in below the floor structure; thus maintaining the floor of the crib as dry as possible and away from the moisture which is likely to pass through the floor structure if it were placed directly on the ground.

It also desirable to make the floor structure so as to permit a corn drag to be placed through the center of the crib so that the corn from the rrib may be carried as is desired.

The crib 10 is provided with a main door opening 12. which may be closed by the hinged door 13.

I will now describe the form WOIl( for the pouring of my floor structure.

In order to provide the piers for supporting the floor structure I provide a number of forms A, which are placed against the crib wall, the wall of the crib forming one side of the Form.

The form A comprises a pair of side members H and an end wall member 15 Which is placed against the inner edges of the sides 14. The outer edges of the sides 14 rest against the crib wall.

In order to hold the form A in position I provide on the sides 14 a pair of straps 16 which have their inner ends projected beyond the inner edge of the sides 14. The projected portion of the straps 16 are each provided with a notch 17.

The end wall member 15 is placed between the projected ends of the straps l6 and across the edges of the sides ll.

A strap 18 having notches 19 therein is then placed against the surface of the end wall 15 and moved to position where the notches l7 and 19 will co-act with each other tor holding the KHOID'I in upright position.

In Figure (5 of the drawings the strap 18 has been shown in position Where it is not in engagement with the strap 16.

The side Walls 14 are provided with up right members 20 preferably of the size commercially known as a The member 20 is provided with a notch 21 in which is received the straps 16 so that the member 20 may rest against the surface of the side walls 14. The upper edge of the member 20 terminates short of the upper edge of the sides 14. The purpose of Which will be hcrcinai'tcr more fully set forth.

The end walls 15 are provided with reinforcing cross cleats 22 which prevent the splitting of the end Walls 15.

The forms A just described are set against the inner surface of the Wall of the crib and in order to hold them properly spaced apart I provide cross members 23 which are preferably of the size and commercially known as a 2 X4.

The ends of the members 23 are placed so that theyrest upon the upper edge of the member 20. The members 23 are thus supported on the members 20 and between the forms A.

The ends of the members are out on a bevel so that they may snugly set against the sides 14 of the forms A. This makes it pos sible to wedge the entire number of forms into position by slightly moving the members 23 towards the center of the crib.

From the construction of the parts just described it will be seen that I have provided forms for piers which will rest adjacent to the Wall of the crib.

It is necessary to provide piers in the center of the crib and this type of forms are referred to by the reference character B.

In the forms B I provide a pair of side members 24 and a pair of end members 25. The end members 25 rest against the edges of the side members 247.

Reinforcing cleats 26 are provided on the end wall members Fixed to the side Wall members 2i are straps 27 which have their ends project beyond the edges of the side members 21-. The straps 2? are provided with notches 38 in their projected portion.

In order to hold the end Wall members 25 to the side wall members 24 I provide straps 29 which have notches 30 Which are designed to co-act with the notch 28 of the straps 27.

From the construction of the parts ust described it will be seen that the end wall members 95 r i gainst the edges of the side wall nirinlir-rs "J5 and lhidi-tll the projected portions of the straps When the straps :25) are placed in pos .ion the form will be rigidly hrld togetl'ier.

Humaorting cleats iii are iixed to the side nn H members 2% and inn. o their ends slightly projm-tcd beyond the oi the side wall members 24. The end wall members 25 are also received between the projected portions of the supporting cleats 51.

The sup 'iorting cleats 31 are designed to support cross bars 32 which are similar in construction to the members The upper edge of the cross bars 32 when in position are iinsh with the upper edge of the form B. The members when in position are flush with the upper edge of the terms A.

In order to provide a drag run Way Within the crib I provide form wail members 33 which have reinforcing cleats 3% fixed thereto. In order to hold the inner walls 33 in proper position I place a member 35 between the reinforcing cleats 34.

Floor boards 36 of any suitable size are then placed upon the cross bars 32, the members :33 and on the walls 33. The floor boards 36 are placed so that the portion where the piers are to be formed are left open. This is clearly illustrated in Figure 5 oi the drawings.

it will be understood that the floor boards may be cut radially it so desired.

A tier the entire form has been set in position the col'u'rctc For the floor and piers is then poured.

From the parts just described it will be seen that the piers and floor structure will be poured integraL The floor structure is referred to by the reference numeral 37 while the outside piers are referred to by the reference :58 and the inner piers by the reierence 39.

The inner end of the run way which is formed between the Walls $0 of the floor structure is left open so as to provide an opening ll whereby access may be had into the run way from the inner end.

When the Hour structure is poured shouldcrs 42 are provided on the walls 40. The shoulders receive iioor boards 43 when it is desired to shovel the corn from the crib without the use of a drag.

In order to gain access into the crib below the floor structure for the removing of the terms, and for gaining access to the opening 41 I provide door opening 44 which is provided with a hinged door 45.

It will be understood that after the floor structure and piers have been permitted to set it is necessary to remove the forms. By the arrangement of the forms which I have provided it is only necessary to remove the strap members 18 and 29 from the pier forms and to drive the members 23 outwardly or towards the wall of the crib. This permits the entire floor boards and forms A and B to come apart and to be free from the floor structure. The forms may then be taken from below the floor structure through the door opening 44.

The door is preferably made of sheet metal so as to prevent any mice from passing into the crib from below the floor structure.

Ventilated blocks of the type heretofore referred to are placed so that ventilation may pass into the crib below the floor structure.

A door 46 preferably made of sheet metal is designed to be used for closing the lower portion of the door opening of the run way when a corn drag is not being used.

The crib 10 is provided with a hub or band 4-? which is designed to hold the blocks of the crib in proper position. Between the band 47 and the wall of the crib I place a sheet metal apron 48 which is curved in cross section and extends away from the crib wall.

The sheet metal apron 48 will prevent any mice from passing up the side of the crib.

It will be seen that I have provided a floor structure of a crib which may be ventilated from below and which is elevated above the ground level and supported upon a number of piers which floor structure and piers are all poured by a single pouring.

It will also be seen that I have provided forms for the floor structure and supporting piers which are collapsible and which may be readily and easily assembled without the use of nails or the like.

Some changes may be made in the construction and arrangement of the parts of my crib without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
